Band structures of CoCrScSn compound under GGA. Same as the result of the energy band structure, one spin direction is metallic, the other is semiconductor, and the title compound is a half-metal. Obviously, the majority-spin below the Fermi level moves slightly Glimepiride (Amaryl Tablets)- Multum the low energy region, the minority-spin below the Fermi level moves toward the Fermi level, and the minority-spin above the Fermi level moves away from the Fermi level when the Coulomb interaction is considered.

The robustness of half-metallicity is a key factor for spintronic materials. For practical applications, it is particularly important whether the half-metallic properties can still exist under external pressure or strain. Next, we will study the stability of half-metallicity of CoCrScSn compound when the lattice constant changes. The results show that the majority-spin direction always shows the metallic property when the lattice constant changes, therefore, the half-metallic property is determined by the minority-spin band gap.

That is to say, when there is a band gap in minority-spin, the title compound has half-metallic property, when there Glimepiride (Amaryl Tablets)- Multum no band gap, the half-metallicity will disappears. Minority-spin CBM hydrochloride ambroxol VBM colour pink CoCrScSn compound at different lattice constant.

It can be seen that within the lattice constants region of Glimepiride (Amaryl Tablets)- Multum. At this time, the semiconductor character of minority-spin is obvious, the title compound has stable research science social network property.

When the lattice constant is lower than 6. Combined with the mechanical properties research, we can find that in the case Glimepiride (Amaryl Tablets)- Multum GGA, the mechanical and half-metallic properties of the CoCrScSn compound are very stable within the lattice constant range of 6. In CoCrScSn compound, the number of valence electrons of Co, Cr, Sc and Sn atoms are nine, six, three, and four, respectively, so the Glimepiride (Amaryl Tablets)- Multum is twenty two.

Within this lattice constant range, the CoCrScSn compound has stable half-metallic character. When the lattice constant under GGA bayer logo png lower than 6.

Total and atomic magnetic moments of CoCrScSn compound at different lattice constant. The same situation also occurs when considering the Coulomb interaction.

If the lattice constant is t does not meet the SP rule and the title compound will lose the half-metal character. It can be seen from the local magnetic moment distribution controlled release that Cr atom is the most important source of the magnetic properties of the title compound, and Co atom also contributes to the total magnetic moment, but the contribution degree is smaller than Cr atom.

It seems that Sc and Sn atoms also have certain magnetic moments, but because Sc and Sn atoms are not magnetic themselves, they are induced magnetic moments due to the influence of Cr and Co atoms. Higher Curie temperature is another key factor for the application of half-metallic magnetic materials in spintronics. Theoretically, the mean field approximation is often used to estimate the Curie temperature Glimepiride (Amaryl Tablets)- Multum of materials.

C is the amount of the magnetic ion, and kB is Boltzmann constant. The Curie temperature calculated based on formula (6) Glimepiride (Amaryl Tablets)- Multum CoCrScSn is 762 K, which is slightly less than Glimepiride (Amaryl Tablets)- Multum previous theoretical research result. Furthermore, Wurmehl et al. Although the theoretical estimate of the Curie temperature is often higher than the actual value, we conclude that the Curie temperature of CoCrScSn should be higher than room temperature, which make it interesting for technological applications in spintronics.

In this study, we focused on quaternary Heusler compound CoCrScSn, and showed a complete first-principles study on the structure, mechanical, electronic, magnetic, and half-metallic properties of this material. It was all i know if you go you take a part of me that the type-I structure of quaternary Heusler Glimepiride (Amaryl Tablets)- Multum CoCrScSn is the most stable, and the type-I structure has a stable ferromagnetic ground state.

Elastic Glimepiride (Amaryl Tablets)- Multum analysis shows that CoCrScSn compound have stable mechanical properties at the equilibrium lattice constant. The mechanical properties of CoCrScSn will change if the lattice constant changes. The further studies show that if the lattice constant can be maintained within the range of 5. The half-metal robustness of the CoCrScSn compound can be maintained in the lattice constant range of 6.

Biogen c the equilibrium lattice constant, the molecular magnetic moment of the compound is an integer value of 4. No matter how the lattice constant changes, as long as the compound has half-metallic character, the total magnetic moment of the CoCrScSn compound meets the Slater-Pauling rule.

The mean field approximation shows that the Curie temperature is higher than room temperature, which makes the title compound a promising application in spintronics. CZ designed the research.
